The study of plastic deformation in the pair of ball-seat of oil well pump

S.A. Gasimova - Azerbaijan State University of Oil and Industry

The paper analyzes the operation of unit of seat-ball on oil well pump. The stressed-deformed state of seat-ball has been theoretically studied. It was established that one of the major reasons for the breakdown of the valve unit is the deformation of seat edge. Considered the mentioned above, a design of valve unit allowing eliminating the probable deformation of the seat from ball beat is offered. The design offered has been tested and initial positive results obtained as well.
